Almost 3 years ago I took my 1987x Plexi Reissue into the studio where started sparking as soon as I turned it on. Finally got around to taking it to a highly recommended tech who found that somehow two terminals in one of the power tube sockets had arc'ed, blowing out the power tubes and damaging some downstream components while at it. $600 bucks later, I picked up today. Its fucking loud as hell, but pure Rock and Roll heaven. Even plugged into the new 1x12 cab its too loud for this room, but at least its tolerable in this room and would probably be OK in a smaller venue. Through the 1960A 4x12 it needs a pretty decent sized room to open it up. Through either cab though, with the channels jumped and the volumes blended somewhere around 1 and 2 O'clock, just pure Marshall tone for days. For what Foggy found it for me plus the $600, I'm still about a grand under what these go for used now days.
